CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 561,543, dated June 2, 1896.

Application iiled November Z7, 1895.` Serial No. 570,277. (No model.)

To aZZ whom it may con/cern.:

Beit known that I, HENRY DEITZ, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Couplers, of which the following is a specification.

My invention relates to that class of couplers known as the Master Car-l3uilders ver- 'Io tical-hook type, and has for its object to produce a coupler of certain special merits, as will be described herein.

Certain features disclosed in this application are not herein claimed, for the reason that they form a part of the subject-matter of my applications, Serial Nos. 567,710 and 568,021, filed November 2, 1805, and November 5, 1895, respectively.

Reference will be had to the accompanying zo drawings, in which- Figure 1 is a plan sectional view on line 1 1 of Fig. Fig. 2 is a transverse sectional vertical view on line 2 2 of Fig. 1. Fig. 3 is a vertical longitudinal sectional view on line 3 3 of Fig. 1. Fig. .4 is a similar view to that of Fig. 3, showing two positions of locking-pin. Fig. 5 is arear view of the locking-pin. Fig. (i is a side view of the coupler in position in car, showing safety device.

In the drawings, A designates the ordinary vertical-hookcoupler casting provided with the special devices of my invention, which relate to the locking devices for locking the knuckle B.

P designates the locking-pin, which is interposed between the end B of the knuckle and the wall A of the casting A, Figs. 1 and 3, and thereby locks the knuckle B. In the front face of pin P there is a slot P, having 4o the inclined bottom, asis shown at P2, and on the inside of the front wall of the casting A there is a projection A2, which engages the Vslot P of pin P in the vertical movement of the pin. This project-ion A2 is for the purpose of preventing the accidental displacement of the pin P, and also for engaging` the inclined end P2 of the slot P in pin P and thereby producing an inclination of the pin in its upward extreme position in order that 5o its lower end I3 may engage the end B of the knuckle B, and in aid of which there is nia-de a lip P4 on the pin and a recess B2 in l the knuckle. On the front top side of pin there is a lip P5, engaging a rounded projection As of casting A, which acts as a center about which the pin swings in automatic locking. On rear side, at the lower end of pin P, there is the projection P6, which is for the purpose of engaging the rebounding lug A4 of casting A (see Fig. 4:) and thereby pre venting displacementV of the pin by sudden vshocks in coupling, as it will be noticed by Fig. 4L that in position of full lines in said iigure the pin P is locked from further vertical lifting by reason of the knuckle end holding projection P6 of pin to engagement of the rebounding lug A4, and this position of pin P is at the time of the greatest shocks in coupling, and this position is maintained through the period of the movement of the knuckle end B' while in contact with the pin in coup ling-say during the movement of the knuckle through angle c d e. i

In the projection P6 of pin is a recess P7, which engages a rib A5 of casting A on the backward swinging of the pin P, and this rib A5 is curved and inclined in a manner to lift the pin bodily by its backward swing to positionof full 4lines in Fig. 4, the purpose of .which is to give a greater depth for the fall of the center of gravity of the pin in swinging home in automatically locking the knuckle, thereby insuring a 4certainty of the pins swinging and falling home in locking.

On the top of the deadblock F there is fastened a safety-chain G, connected to pin P, the purpose of which is to lift the locking-pin P in the event of the coupler becoming detached from the car, and thereby unlock the knuckle and uncouple the train and hold the coupler to car and prevent its falling on track and derailing train, as is the result when the ordinary coupler of this class is detached from car during movement of train. This safety unlocking of pin is produced by the inclined portion PS of pin P.

The coupler is unlocked by the cutting-out lever L lifting the pin vertically to its limit and then immediately releasing lever, whereupon, by the inclining of the pin, as before described, the pin rests on the top ef the end B of knuckle B and the coupler is ready to uncouple at any time thereafter, suiting the convenience of the trainmen, and upon the IOO uncoupling of the knuckle the pin P falls home, and in the coupling again the pin is swung backward and upward by the knuckle end, thereby permitting the knuckle to return home, and on the knuckles arriving home the pin drops and swings in past the knuckle end, locking the same automatically. The pin is lifted out by swinging it in position of dotted lines, Fig. 4, clearing projection A2 of casting A. The slot P being in the front of piu P and in the plane of its oscillation insures the safety of projection A2, since no movement of violent nature can cause pin P to engage projection A2.

l. In a coupler of the class described the combination of locking-pin having a slot in the forward edge of said pin being in a vertical longitudinal plane of the coupler with a projection on the inner side of the forward wall of the main coupler-castin g for engaging said slot.

2. In a coupler of the class described the combination of a locking-pin, having a slot in the forward edge of said pin, being in a vertical longitudinal plane of the coupler, and having an inclined bottom to said slot, with a projection on the couplercasting for engaging said slot to prevent the accidental displacement of said pin in the manner shown and for the purpose described.

f3. In a coupler of the class described, the

combination of a locking-pin with an inclined lifting-rib whereby by the backward swing of the pin in contact with the incline, the pin is lifted in the manner shown for the purpose described.

4:. The combination'of a locking-pin, provided with a projection P6 on said pin, and a rebounding projection A4 for the purpose described.

5. The combination of a locking-pin having a recess P7 in the end of said pin with an inclined rib A5, said rib and recess fitted to each other in a manner to bring the pin in the proper plane to swing home on clearance of the knuckle.

6. The combination of a locking-pin, having a slot in the forward edge of said pin being in a vertical longitudinal plane of the coupler, said slot having an inclined portion at its lower end, with means for engaging said slot, whereby the pin is so inclined in a moment to engage the knuckle end for the purpose described.

In witness whereof I have hereunto subscribed my name, on this 16th day of November, 1895, in the presence of two witnesses.
